A spout 13 ofthe trough 11 is projected through a suitable opening in the body portion l so as to permit the trough to be filled from the inside of the room.

Theouter surface of the body portion 1 is provided with vertically extending projec-l tions 14 above each of `which is pivoted a` bar, U-shaped in cross section andadapted `to be moved over the projections14, as-

shown in Fig. 3,\so as to clamp asheet of material between said projections.`

WFor ordinary usage,such as in sleeping roomsymy invention may be applied to the window and the `desired amount of air permitted to filter through theopenings therein by the adjustment of the slides 6." How- 'ever'2 1n sick-rooms it may be desirable to :medicate or sterilize air entering the room.

In such instances the trough 11 may be partially filled, through the spout 13, with a and effectively filtering and charging the air flowingthrough the opening with the vapor of the liquid in the trough.
